  • Abstract This thesis is intended to apply an independently controllable transmission (ICT) mechanismto the gearbox inhybrid electric vehicles. The ICT mechanism consists of two planetary gear trains and two transmission-connecting members. This mechanism has four terminals, including a motor, an engine, an output and a generator. It also has a dual input and a dual output, and can be appropriately switched to a triple input and one output in such a way as to receive higher degrees of freedom and integrate power flows more smoothly. This way, the powers of the engine and the motor can be integrated together.There are three different types of power supplies I have investigated under the mechanism, depending on different situations. The first type is that when a vehicle is driven, only the motor delivers the necessary power to the output shaft. In the second type, both of the motor and the engine simultaneously transmit power to the output shaft. The third one is the deceleration of a vehicle, a vehicle whose velocity gradually decreases into which torques and energy flows are inspected.
    Hybrid electric vehicles sold on the market today have a hydraulic torque converter each. By way of theoretical derivations and experimental verifications, we argue that using the ICT mechanism, rather than the hydraulic torque converter, can meet the demand for the gearbox. In addition, the application of the mechanism to the gearbox in hybrid vehicles can avoid infringing the patent (JP2005329842) on the planetary gear train of Toyota Prius.
    In this study, I would do a feasibility analysis by way of the existingequipment, designed and assembled an ICT mechanism, and proposed an experimental platform based on kinematics and dynamics. Ialso conducted three different experiments to do theoretical analyses of rotating speed, torques and power flows, as well as constructed an experimental platform to observe torques and power flows.
